The government has asked the U.S. Embassy in Seoul to produce strong measures to address the increasing number of crimes by U.S. soldiers in South Korea.

The Foreign Ministry said director general of its North American Bureau Lee Baek-soon on Sunday called in the U.S. embassy’s minister counselor and expressed deep regret over recent crimes involving U.S. soldiers.

The U.S. reportedly agreed on the need to address the issue and promised to look into the cause of increasing crimes and produce proper measures.

A series of crimes involving American soldiers stationed in South Korea have occurred recently, including a beating of a South Korean police officer by an American private second class on Sunday.
